Dr. Ciaran Byrne:

I will give the example of a terraced home which is mass concrete, 1930s with a BER F rating. This is a cost taken from a pilot scheme we did last year. The install cost would have been €36,000. On the current one-stop-shop, OSS, grant levels which were announced in February, the homeowner would have received €18,600 in grants, which is around 50%.
